Definitions

  • the invention relates to an integrated intake system according to the preamble of the main claim.
  • intake systems include a variety of components such as intake manifold, throttle valve, idle actuator, fuel distribution, injectors, temperature sensor, etc.
  • a system is known from Siemens AG in which the different components are flanged or arranged on a plastic carrier.
  • the plastic carrier is designed as an intake pipe.
  • a characteristic of the core melting technology is the overmolding of a metal core, the melting point of which is below the plastic.
  • the suction tube By melting the core, the suction tube can be produced from a single casting with largely free shaping, high dimensional accuracy and good surface reproduction.
  • an intake pipe is known, which is constructed in two-shell technology.
  • the two shells are connected to one another in that they are encapsulated with plastic in an additional operation at their connection points.
  • This process is very complex and requires an additional operation to connect the two parts.
  • the connection technology does not guarantee a reliable seal between the two parts - as practice has shown.
  • An intake system is also known from Revue Technique Automobile, Volume 48, No. 555, page LX. This consists of a large number of elements in which - similar to the system from Siemens AG - the various components are flanged or arranged on a plastic carrier. Here, too, the plastic carrier is designed as an intake pipe.
  • the invention has for its object to provide an intake system, in particular for combustion air of an internal combustion engine, which is simple to manufacture and contains a large number of components.
  • a major advantage of the invention is the use of multi-shell technology. In this process, several individual parts are injection molded, which, when welded together, result in the finished product.
  • the product In the case of the intake system, the product consists of a lower and an upper part, with the parting plane between the lower and upper part running along the intake pipes.
  • One embodiment of the invention provides for the upper part of the housing to be provided with a further intermediate housing, the two parts being connected by welding. Vibration welding has proven itself as a welding process. By arranging an intermediate housing, air-guiding ducts can be formed or other components can be linked to the intake system.
  • an oil separator for the crankcase ventilation is integrated in the lower part of the housing. It was previously customary to arrange an oil separator as a separate plastic component on the engine, but it is now possible to enclose it in the plastic housing.
  • the design of a resonance system in the intake system is possible in a simple manner. This requires two air duct systems that can be connected or disconnected with a resonance flap.
  • Switching intake pipes can also be produced with the intake system according to the invention by adapting the intake pipe lengths to the speed of the engine by means of appropriate flaps or valves.
  • the resonance flap in the lower speed range can be used to divide the row of cylinders, creating two separately aspirating 3-cylinders, which have more favorable torque behavior, especially in the lower speed range.
  • the resonance flap opens and enables the optimal use of the power of the 6-cylinder engine.
  • a further optimization of the torque behavior can be achieved by designing the intake system with a turbulence system.
  • This turbulence system consists of an independent turbulence collector and independent turbulence channels. These run parallel to the intake ducts and, like these, are formed from the upper and lower shells of the housing.
  • the turbulence system is effective at low engine speeds, that is, in this speed range, the intake air of the engine is supplied exclusively via the turbulence system, which, due to smaller cross-sections, leads to better swirling of the intake air and thus to better mixture formation.
  • the intake system can be equipped with a multitude of components, such as, for example, a hot film air mass meter, injection valves and fuel rail.
  • the throttle valve can also be integrated in the system.
  • the system integration has the advantage that all connecting lines, namely both the electrical and the connecting lines for fuel, can each be connected to the peripheral engine components with a single plug contact or a plug connection.
  • the integrated intake system shown in FIG. 1 contains all the components that are required for the preparation and conditioning of the fuel mixture, from the intake air to the inlet valves of the internal combustion engine.
  • the suction system consists of a housing 10 which has a base body 11 on which a cover 12 is detachably fastened. The following components are contained within the housing; An oil separator 13, to which the blow-by gases of the internal combustion engine are supplied according to arrow 14. The blow-by gases are cleaned in the oil separator 13 by means of a filter element 15. The oil flows back into the oil pan in the direction of arrow 16, while the cleaned gases are mixed with the intake air according to arrow 17.
  • a resonance flap 36 is arranged in the base body 11 and a filter element 21 in the form of a rectangular filter.
  • the suction pipes 23 connect to the base body. These suction pipes are equipped with the injection valves 24. The supply of the injection valves 24 takes place via a fuel distribution bar 25.
  • the intake air flows through the intake port 26 into the housing according to the arrows 27, enters the unfiltered air space there and flows through the filter element 21 according to the arrows 28.
  • the cleaned air flows through a sieve 29 and reaches the throttle device 19 via the air mass meter 18.
  • the air flows through the air duct 30 and from there into the transverse distributor 31. According to the arrows 32 and 33, the air flows into the two resonance chambers 34, 35 Resonance chambers are separated via the resonance flap 36.
  • the resonance flap is opened at high speeds and connects both chambers to improve the torque behavior. Starting from the resonance chambers 34, 35, the air flows through the intake manifolds 23 to the intake valves of the engine, not shown here.
  • the structure of the housing is shown in a sectional view according to FIG.
  • the base body of the housing 10 consists of a lower part 37, which also forms the lower half-shell of the suction pipes 23. This lower part is welded to an upper part 38.
  • the upper part 38 forms the upper half-shells of the suction pipes 23 and the resonance chambers 34, 35.
  • the resonance flap 36 is arranged in the resonance chambers, which can be pivoted through 90 ° via an adjusting mechanism (not shown here).
  • the air duct 30 is fastened to the upper part by means of a screw connection.
  • the air duct 30 is provided with a cover 40. This is expediently fixed to the channel 30 by means of a welded connection.
  • the throttle device 19 is integrated into the air duct, as is the air mass meter 18, which is only indicated schematically here.
  • the filter element 21 is located between the cover 12 and the upper part 38 of the housing and seals the unfiltered air space 41 from the clean air space 42 in a filtering manner.
  • Fastening elements 43 are arranged on the suction pipes 23. These fastening elements 43 carry the fuel rail 25, which supply the injection valves 24 with fuel.
  • FIG 3 shows a schematic representation of the intake system with an integrated turbulence system. Especially with lower ones Speeds of the internal combustion engine, it is necessary to sufficiently swirl the intake air supplied with the fuel to optimize the combustion process. This is best done through high air speeds. In order to achieve these high air speeds, a so-called turbulence system can be integrated in the intake system. This is basically a reduced intake system, which corresponds in function to the intake system, but generates higher air velocities due to the smaller duct cross sections.
  • the intake manifold 26 is shown with the air mass meter 18 and the air duct 30, which the two resonance chambers 34, 35 and the suction pipes 23 are connected downstream.
  • the air required is guided from the intake manifold via air guide channels 44, 45 to a turbulence collector 46.
  • Six turbulence channels branch off from this turbulence collector 46 (channels 47, 48, 49 50 are visible). These turbulence channels run parallel to the intake pipes 23 and open into the intake tract of the cylinder head of the internal combustion engine in the area of the intake valves.
  • the throttle valve which is not visible here, is designed as a register throttle valve 51, which first releases the turbulence system at low speeds and only opens the main system at higher speeds.
  • the turbulence channels are also built using two-shell technology. This means that the lower half-shell of the turbulence channels adjoins the lower half-shell of the suction pipes, while the upper half-shell connects to the upper half-shell of the suction pipes and the half-shells are welded together.
